The last confirmation of love when everything else fell away

This passage from the book I’m reading reminded me of my siblings:

…People talk about the happy quiet that can exist between two lovers, but this too was great: sitting between his sister and his brother, saying nothing, eating... He did not consider if or how or why he loved them.  They were just love: they were the first evidence he ever had of love, and they would be the last confirmation of love when everything else fell away.
